I have an MX-850 with an MRF-350. It has been working fine until this morning, when we tried to turn the TVs on. I just changed the batteries on the remote, and when I attempt to make an action, the signal icon lights up on the remote. However, neither the "status" light on the base station, nor the "RF" light on the received light up. I've unplugged the base station, and the "status" light flashes three times when I plug it back in. Any thoughts?
